MATHEW WISE, OF ATHENS, OHIO.

TRUSS.

SPECIFICATION forming part of Letters Patent No. 440,083, dated November4, 1890.

Application filed April 12, 1890. Serial No. 347,633. (No model.)

To all whom it may concern:

Be it known that I, MATHEW WIsE, a citizen of the United States,residing at Athens, in the county of Athens and State of Ohio, haveinvented certain new and useful Improvements in Trusses; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to trusses and aims to provide a truss that willdispense with back-pressure pads, and which will not exert any pressureon the spinal column, and which will adapt itself to every variety ofmovement of the wearer.

A furtherobject of the invention is to dispense with pistons orguide-rods of any kind between the pad and the body-band and to reducethe number of parts to a minimum.

The improvement consists of the novel features which hereinafter will bemore fully described and claimed and which are shown in the annexeddrawings, in which Figure 1 is a perspective view of a truss embodyingmy invention. Fig. 2 is a section through the pad and band on the line XX, of Fig. 1. Fig. 3 is a rear view of the pad.

My improved truss may be briefly described as consisting mainly of ametallic band A, made of medium oil-tempered steel, made to fit the bodyaround the hips, and open in back, not extending so far as to come incontact with spinal column, thus doing away with any pressure-padsbehind, having in fronta drop or loop extending across the front ofbody, giving perfect and easy movement of the body, the band from dropor loop back to be covered by leather, chamois, or other suitablematerial, and fastened behind with a strap and buckle, and the drop orloop to be made to extend centrally over the hernia. The pressure-pads Bfor hernia are attached to this drop or loop by means of links or cuffsO 011 band. The links or cuffs are made so that they can be moved to anyposition required, and are held to position by means of set-screws b,which pass through outside of link or cuff and have bearing on band, theset-screws 1) coming even or flush with surface of links, leaving noprojection for clothing to catch upon, the links or cuffsO clamping oninside the foot of springs D, connected with pressure-pads E, whichholds hernia to its proper place.

The pad E consists of hard rubber, or any metallic substance, which ismade hollow or concavo-convex.

Around outer edge of cavity there is a groove 6 in pad which holdsbottom coil of the coneshaped spiral spring D, which has a foot cl onopposite end, which rests against inside of band through link or cuffheld in place by means of set-screw and link heretofore described, thisspring being fastened to pad by being sprung into aforesaid groove 6 inpad, thus making all bearing or pressure from spring on outer edge ofpad. The advantage of this is, there are no guides or pistons requiredconnecting pad with spring or band, the spiral spring being made in coneshape and attached to pad in this way, so that as pressure comes on padsthe spring will close down into cavity in pad. The footof spring, beingcentrally attached to the link or cuff, holds pad so that it allows nochance of displacement of hernia.

Having thus described my invention, what I claim and desire to secure byLetters Patent,

1. The combination, with a concavo-convex truss-pad having annulargroove 6 around the outer edge of cavity, as shown, of a conical springhaving its base-coil sprung into the said groove 6, substantially asdescribed.

2. The hereinbefore-specified truss, composed of the body-band oftempered steel having a drop loop in its front side and having a spacebetween its rear ends, the cufi on the depressed part of the band, thebindingscrew for holding the cuff on the band, the pad having recess inits rear side and having a groove in the sides of the recess, and thecone-shaped spring having its last coil sprung in the said groove andhaving a foot which is inserted in the cuff between it and the band,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
